Security Bulletin

Summary

There are multiple vulnerabilities in IBM SDK Java Technology Edition, 
Versions 6 and 7 that are used by IBM InfoSphere Information Server. These 
issues were disclosed as part of the IBM Java SDK updates in January 2016 and
includes the vulnerability commonly referred to as SLOTH.

Vulnerability Details

CVEID: CVE-2016-0475

DESCRIPTION: An unspecified vulnerability in Oracle Java SE Java SE Embedded 
and Jrockit related to the Libraries component has partial confidentiality 
impact, partial integrity impact, and no availability impact.

CVSS Base Score: 5.8

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/109946 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:N)

CVEID: CVE-2016-0466

DESCRIPTION: An unspecified vulnerability in Oracle Java SE Java SE Embedded 
and Jrockit related to the JAXP component could allow a remote attacker to 
cause a denial of service resulting in a partial availability impact using 
unknown attack vectors.

CVSS Base Score: 5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/109948 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-7575

DESCRIPTION: The TLS protocol could allow weaker than expected security caused
by a collision attack when using the MD5 hash function for signing a 
ServerKeyExchange message during a TLS handshake. An attacker could exploit 
this vulnerability using man-in-the-middle techniques to impersonate a TLS 
server and obtain credentials. This vulnerability is commonly referred to as 
SLOTH.

CVSS Base Score: 7.1

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/109415 for the current

CVEID: CVE-2016-0448

DESCRIPTION: An unspecified vulnerability in Oracle Java SE and Java SE 
Embedded related to the JMX component could allow a remote attacker to obtain
sensitive information resulting in a partial confidentiality impact using 
unknown attack vectors.

CVSS Base Score: 4

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/109949 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:S/C:P/I:N/A:N)

a fixed, supported version/release/platform of the product.

For HP-UX versions, contact IBM customer support for information on 
vulnerabilities other than the Sloth vulnerability CVE-2015-7575.

Workarounds and Mitigations

For CVE-2015-7575: Users of Java 7 and later can address the issue by updating
the /jre/lib/security/java.security file as follows (both steps are required):

 Add MD5 to the jdk.certpath.disabledAlgorithms property - e.g. 
jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024, MD5

 Add MD5withRSA to the jdk.tls.disabledAlgorithms property - e.g. 
jdk.tls.disabledAlgorithms=SSLv3, RC4, DH keySize < 768, MD5withRSA

Java 6 requires code changes in the JSSE component in addition to the 
java.security file modifications, so upgrading the JDK is the only solution.
